Zusammenfassung:New compounds for making a hydrophilic surface lipophilic. The compouns have general formula (I), wherein Z and Z independently is chlorine, fluorine, bromine, alkoxy with not more than 6 carbon atomes, NH, -NH2, -NR2, wherein R' is alkyl with 1 to 3 carbon atoms, -SH, -CN, - N3 or hydrogen, and R is formula (II), wherein each S-substituent which can be the same or different is hydrogen, whereby the phenyl ring may contain at the most four hydrogen substituents, alkyl with 2 to 4 carbon atoms, or methyl or methoxy, in which case there may be at the most three hydrogen substituents in the phenyl ring, cyano, ethoxy, or two adjacent S-substituents form with the phenyl nucleus a naphtalene or anthracene group, or three adjacent S-substituents form together with the phenyl nucleus a pyrene group, and X is the group -(CH2)n , wherein n is 0 to 20, preferably 10 to 16, or the group (III), wherein i is 0 to 10 and k is 1 to 5, whereby, when n is not 0, i.e. X is a spacer group, the S-substituents, especially S3, can also be phenoxy or biphenyl, and R is equal to Z or R , or is lower alkyl, lower alkenyl, phenyl, or phenyl substituted with lower alkyl or lower alkoxy. The novel compounds may be used as such for modifying the hydrophilic surface for a variety of purposes, such as for chromatographic purposes or for use in electronics, or the compound may be polymerized, optionally using as coreactants known silanes, to form polymers especially well suited for chromatographic purposes. De nouveaux composés utilisés pour rendre lipophile une surface hdyrophile ont la formule générale (I), dans laquelle Z1 et Z2 sont, indépendamment, du chlore, du fluor, du brome, de l'alkoxy ayant au maximum 6 atomes de carbone, NH, -NH2, -NR2, dans lequel R' est de l'alcoyle avec 1 à 3 atomes de carbone, -SH, -CH, - N3 ou hydrogène, et R1 a la formule (I), dans laquelle les substituants S, qui peuvent être indentiques ou différents, sont de l'hydrogène, alors que la chaîne phényle peut contenir au maximum quatre substituants d'hydrogène, de l'alcoyle comprenant entre 2 et 4 atomes de carbone, ou du méthyle ou du méthoxy, auquel cas il y aura au maximum trois substituants d'hydrogène dans la chaîne phényle. Du cyano, de l'éthoxy, ou deux substituants S adjacents forment avec le noyau phényle un groupe naphtalène ou anthracène, ou trois substituants S adjacents forment avec le noyau phényle un groupe pyrène, X étant le groupe -(CH2)n$(1,4)$, dans lequel n est compris entre 0 et 20, de
